Why Tolerance Matters in Aluminum and Stainless Steel Fabrication

Share

Metal fabrication requires high tolerancesHow do you define the quality of your fabricated metal products? Do you track factors like manufacturing speed or cost? Perhaps you rely on end users to let you know when you’re doing a good job. Regardless whether you’re primarily concerned with economic feasibility, timetables or public opinion, tolerance is the underlying metric that makes superior metal fabrication possible.

What Is Tolerance?

In the world of precise engineering, tolerance is a measurement that gauges how much of a deviation from the target is acceptable. For instance, suppose you’re creating a part that’s meant to be 50 mm long. A tolerance of ±1 mm would mean that it could still function adequately if it were actually between 49 and 51 mm long.

There are various ways to measure and specify tolerance ranges, but the end goal is usually the same. By ensuring that part dimensions never fall outside of predetermined limits, you can create hardware that’s guaranteed to be compatible with other components. This concept is essential to manufacturing products that fit together correctly and fulfill functional roles in machinery.

Tolerance in Metal Fabrication

Why bother with tolerances at all? Isn’t it better to hit the mark exactly every time? Although this would certainly be ideal, it’s unrealistic.

Even the best manufacturing processes carry inherent imprecisions. For instance, a computerized lathe or bending machine may appear to perform the same actions time and again, but these devices are only rated for a certain degree of accuracy. Whether it’s the result of tool wear, operator error or even environmental factors, like temperature fluctuations, deviation is a fact of life.

How Can You Ensure That Parts Shops Meet Your Tolerance Requirements?

When you supply a manufacturer with a schematic diagram, you usually include tolerance values. These figures allow the fabricator to finely tune their hardware settings to ensure that the machinery operates within desirable parameters. Smart manufacturers also use tolerances with regular process monitoring to detect inaccuracies before they result in thousands of incorrectly formed parts.

Changing the way you manufacture parts can also improve adherence to tolerance. For instance, metal fabrication processes that minimize the number of steps required to go from a raw piece of stock to a finished product can dramatically reduce the likelihood that unexpected imprecisions will crop up along the way. A machinist with a well-calibrated tool stands a better chance of creating uniform work if they’re able to do everything without having to switch to a device that might not accurately replicate the same settings. Similarly, keeping all of your fabrication in one workshop can help you control the output with a far greater degree of consistency.

What You Stand to Gain From Better Tolerance Compliance

Parts that fit and function correctly don’t just make your consumers happier. They also benefit your bottom line by reducing material waste. When your manufacturing processes exhibit fewer failures, you have fewer duds to throw away. You can also streamline procedures like assembly and product maintenance because you know what you’re working with every time.
